These are all great remixes, and I love how it progresses all as one song. All the transitions feel very natural. The only critique I really have is that a few of the chords in your Boss Battle section sounded a little inaccurate, particularly during the ascending part. But they're some tricky chords, and I would have had trouble with those too. I'm only picky about that because I've played the living balls out of that game lol
